i have all ready done a restore and it did nothingIf you get this error on boot, restore a NAND backup. If you don't have one try the recovery mode. This will remove a9lh and possibility sighax and update you to 11.4.
Use a hardmod or dsiware hack to install sighax.

BTW did you get sighax installed successfully?
im right next to it and the light is blinking on the 3dsMake sure you Wi-Fi is on. (blinking LED).
